What I did I've changed auto focus motor instead of front element. You need to have some soldering skills as soldering will be required. I think it's gonna be hard to remove front element (front cap) if I would be in that situation I would go for auto focus motor change, not front lens.

Hope that was clear enough if not will send you pm then you can reply to it

Tbh will be easier for you to replace just af motor as you have two same lenses. I did af swap from 50-135 to 17-70 if you'll gonna have any questions send me pm
